Reg T VS Portfolio Margin

I trade with IB and I am thinking of changing over to Portfolio Margin next week and would like to get some feedback on the pros and cons.

My thinking is that I can sell some EFPs and earn a little bit more interest on my money and with Portfolio Margin I will only required to tie up Less than 1% (I think based on the information on IB)of my funds for margin.

With Reg T it appears that I will tie up a lot more of my funds and have lower leverage.

I mostly day trade and almost never carry overnight a long position. I do once in a while carry over a short position overnight but I will not have to pay interest on that anyway.

From What I read on the IB website I will still only get about 3X intraday leverage on shorts but I have also read that the actual leverage could be less with portfolio than with Reg T so I am wondering if anyone has had some experience doing what I am thinking of doing.

Try the "What If PM" button in your account window when you have some typcial positions on and see what effect it has.

Generally, I find it hard to work out the effect of PM, though without doubt it seems to give far higher leverage, about 6:1. It's useful when holding both short and longs and unusual because seems to NOT want an equal proportion of shorts and longs, to make for optimal leverage
